APPARATUS FOR STOPPING LEAKS,

- SHIPS HULLS.

Application filed April 5, 1927. Serial No. 181,210, and in Germany March 31, 1926.

This invention relates to an apparatus for stopping leaks especially in the botom. and side walls of ships? hulls and comprising a spindle guided in the apex of a hood placed is placed over the leak is on the ships hull or bottom Z, sothat it completely-covers the leak. The arms 6 and the stays h and the spindle 0 are in the positionshown in Fig. 1. In order to stop the leak the spindle c is rotated by means of the hand-wheel 0Z so that it is screwed into the hood I). The arms 6 are lifted and spread at the downward movemnt of the spindle 0 until the pads z' bear from the inside onto the ships hull the hoodibeing strongly pulled onto the outer the ships hullwhich has run aleak and covering the circumference'of the leak and having an edge that is sealed watertight when pressed against the ships hull. A hand wheel is fixed on the outer end vof the spindle and arms are hingedly fixed on the iner end of the spindle. and designed, when said spindle is rotated, to be spread under the influence of draw-stays hingedly connected vat the one end to a nut which guides the spindle and at the otherend each to one of said arms. The arms are thus pressedonto the inner side of the ships hull or bottom. Anembodiment of the invention is shown, by way of example, on the accompanying drawing, in which I a V Fig. 1 shows the apparatus in longitudinal section. t

Fig. 2 is a similar view, showing the apparatus fixed on the ships'hull. vFig. '8 isa plan view of Fig. 2.

The apparatus'consists of a hood I) made .of convenient material, for instance steel, and having an edge, a of rubber. In the apex of the hood I) a screw spindle 0, is screwed. On the. outer end of the screwspindle 0 a hand wheel (5 is fixed. 01i the inner end of the screw-spindle 0 a collar 7 is mounted on which arms 0 are hingedly fixed; In a nut g fixed'on the inner surface of hood 7 Z) the screw-spindle c is guided and stays. h

V are hingedly fixed on said nut. The stays arefurther-hingedly connected at the other end each to one of the arms e. On the free 7 ends of each arm 6 a rubber pad 2' is fixed.

being compressed. "The leak is thus tightly covered andpacked. Convenient means may be provided to ensure the spindle against back-rotation. H

' This apparatus may also be used for stoppingleaks in boilers or the like until they can be repaired. y

' I claim:

in ships hulls and bottom, comprising in 2 the. ships hull. to'cover the leak, a rubber packing on the edge of said hood, a screw spindle screwedinto the apex of saidhood,

hood and serving toguide said screw-spindle,

collar, a rubber pad onlthe outer. surface of upper end to said nut and'at the lower end to a correspondingarm, substantially as described and shown.
